Substack: Pros & Cons
Pros
- + Completely free to start with no upfront costs — zero barrier to entry with all core publishing features available immediately

- + Multimedia platform supporting newsletters, podcasts, video, livestreaming, Notes, and Chat communities in a single integrated experience
- + Strong reader engagement with genuine community interaction through comments, Chat, and Notes — higher engagement rates than typical social media platforms
Cons
- − The 10% platform fee plus Stripe's ~2.9% + $0.30 per transaction creates a 13-16% total take rate that becomes very expensive at scale (e.g., $1,300-$1,600/month on $10K revenue)
- − No email marketing automation, segmentation, A/B testing, or advanced personalization — all subscribers receive identical emails with no conditional logic
- − No public API and zero native third-party integrations — cannot connect to CRMs, e-commerce platforms, Zapier, or other marketing tools
- − Limited design customization with a single standardized template — no drag-and-drop editor, no custom HTML, and minimal branding options
- − Platform can remove content or delete accounts without notice, and customer support is difficult to reach for issue resolution
